f4abb7afc6 MIPS: ES6 symbols: Implement Symbol intrinsic and basic functionality 
Port r13786 (b5e7a82a)

Original commit message:
- Add --harmony-symbols flag.
- Add Symbol constructor; allow symbols as (unreplaced) return value from constructors.
- Introduce %CreateSymbol and %_IsSymbol natives and respective instructions.
- Extend 'typeof' code generation to handle symbols.
- Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols.
- Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method.
- Extend Object.prototype.toString to recognise symbols.

Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).

e4edbb0535 Cleaned up CpuFeature scope handling. 
First of all, it has nothing to do with Isolates, it is related to the assembler
at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up
some platform-specific stuff on the way.

Note that there are some things which still need some cleanup, like e.g. using
EnumSet instead of uint64_t, making Probe() more uniform across platforms etc.,
but the CL is already big enough.

db7591e403 Linux: for use_system_v8=1, use all_dependent_settings 
instead of direct_dependent_settings - with V8 headers
being included in other headers, the former works much better.

This is a configuration that is not used for Google Chrome
neither V8 buildbot, and has been tested for its intended
use case (Linux distributions).
